BTW, have you thought about opening ggplot2 development (provide a  
way to check out the dev code and have the possibility to submit  
patches at least) or do you prefer to keep it a personal project for  
now? I don't know how intricate your research and the development of  
ggplot2 are and would understand that you want to keep in 100% hadley  
wickham if you are to be judged on it academically. But boring work  
such as improving error messages, writing documentation and chasing  
small bugs is probably more efficiently done by a team than by a  
single person, with little free time. Furthermore, most of these  
things can be done without deep knowledge of the architecture of  
ggplot2.
I probably won' t be able to make significant contributions before a  
while but I would be happy to see how ggplot2 progresses and which  
directions are taken by following an SVN tree.
